Monitoring Technique

VARIMETER IMD

Insulation monitor

RN 5897/240

Product Description

The insulation monitor RN 5897/020 of the VARIMETER IMD family

provides best and up to date insulation monitoring of modern IT systems

in an optimum and state of the art way fulfilling the relevant standards.

The device can be used in the most flexible way for AC, DC and AC/

DC systems. The connection to the monitored voltage system is done via

one of the coupling units. The setting of the parameters and the switching

values is done by simple and operator friendly rotational switches on

front of the device. The operating status is indicated user friendly via a

multicolour LED. With a sealable transparent cover the device is protectet

against manipulation.

All Technical Data in this list relate to the state at the moment of edition. We reserve the right

for technical improvements and changes at any time.
